Аннотация:Abstract—Based on a large series (N = 14038) of daily solar-wind densities, we obtained the fluctuation
power spectrum. The spectrum shows that the 399-day variation (the synodic period of Jupiter) has the
largest amplitude in the interval of periods from 20 to 800 day. It is second in magnitude only to the
secular, 22-, and 11-year variations. The amplitudes of the 399-day variations in solar-wind density,
temperature, and speed were determined by a superposed-epoch analysis: ≈ 0.5 cm−3, ≈ 8000 K, and
2.8 km s−1, respectively, at a more than 95% confidence level. This leads us to conclude that Jupiter may
affect the solar-wind parameters, since only Jupiter has a 399-day periodicity in our planetary system.
